Wall tie piece assembly capable of eliminating construction error

Abstract

The invention discloses a wall tie piece assembly capable of eliminating a construction error. The assembly comprises an inner mantle fiber piece pre-buried into concrete in the direction perpendicular to the concrete vertical face to be cast, three blind holes are formed in the inner mantle fiber piece in the axial direction of the inner mantle fiber piece, the axis direction of the inner mantlefiber piece is the direction perpendicular to the concrete vertical face to be cast, the axis of one blind hole is located at the central axis of the inner mantle fiber piece, the axes of the other two blind holes are symmetrically arranged at the upper and lower sides of the central axis of the inner mantle fiber piece, the hole walls of the three blind holes are sequentially provided with unthreaded holes and inner threaded holes connected with the unthreaded holes from exterior to interior, the inner threaded holes are used for being in threaded connection with an outer threaded section ofwall tie pieces to be connected, the length of the inner threaded holes is two times the diameter of the wall tie pieces, the inner diameter of the unthreaded holes is consistent with the diameter ofthe smooth section of the wall tie pieces, the diameter of the inner threaded holes is 0.5 mm smaller than the inner diameter of the unthreaded holes, and through holes running through the inner mantle fiber piece are formed in the inner mantle fiber piece at the rear ends of the blind holes. By adopting the assembly, the wall tie pieces are prevented from being sheared or broken.

Description

technical field [0001] The invention relates to components such as pre-embedded connectors for wall ties. Background technique [0002] The current technology of mechanically connecting the pre-embedded inner sleeve iron parts with the wall tie bars has the following disadvantages: [0003] Inaccurate positioning: Since the technology of pre-embedded inner wire iron parts is to fix the inner wire iron parts on the formwork, it is pre-embedded before concrete pouring. Although the positioning can be carried out on the formwork according to the drawing size, the geometric size after concrete pouring There are errors, so that the position of the future wall tie bars may not be on the same level as the masonry mortar joints, resulting in pre-embedded failure. [0004] Due to the mechanical connection, it is necessary to cover the outer wire on the wall tie, which correspondingly weakens the steel bar area at the end of the wall tie wire, and the concentrated stress is easily ge...

AI Technical Summary

Problems solved by technology

There is only one hole in this method. If the mold expands or the geometric dimensions are not accurate during the pouring of concrete, the position of the embedded part will also be inaccurate, so that it cannot play its due role.

Moreover, this method does not take into account the covering wire on the wall tie, which weakens the area and diameter of the end of the wall tie wire, and it is easy to produce concentrated stress at the junction of the wall tie covering wire and the non-coating wire, thereby making the wall tie break here
